ADAPTIVE, CONTENT-BASED DISCHARGE OF A FIELD EMISSION DISPLAY

摘要

A method is provided for reducing power and audible noise during discharging of dielectric surfaces (137) of a field emission display (100, 200). The method comprises reading (302) a distribution parameter of one or more frames of video data and if (312) the distribution parameter exceeds a threshold, lowering (314) the voltage on an anode (124) and impacting electrons from a plurality of emitters (114) upon the dielectric surfaces (137).
